Letters Patent No. 96,671, dated November 9, 1869.

. The Schedule referred to in these Letters PatentA and making part of the same.

To all whom it may concern:

Be 'it known that we,.JoHN. BUTTERWORTH and.- J AMES BUTTERWORTH, of Trenton, in the county of Mercer, and State of New Jersey, have invented a new and-useful Improvement in Oondensing Carding- Engines, which we denominate a SelfStripper, Strand- Divider, and Fibre-straightener; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon.-

It is well known to cai-ders that great injury and loss result to manufacturers in consequence oi' a portion of the fibresbeing thrown across' the spaces between the rings of the doffers, thus connecting the strands, and delivering them to the rubbers in this.v

connected condition.; Especially is this the case when thespaces upon the doiiers are narrowed up, as becomes necessary in spinning fine yarns; and still more so, when, as sometimes is the case, use has been` made of small 'circular disks having saw-teeth on their peripheries, vin combination with a stripper and the cylinde-1', for the purpose of sawing the entire material that has been thrown uniformly upon both the spaces and rings of the doffer, and vcarrying said material (that has been taken by the saw-teeth in dividingthe strands ou the doffer) to the stripper and to the cylinder,.as inl the condensing carding-engine patented,

l'April 29, 1862, by Isaac Stead. It is obvious that the saw-teeth, operating upon,

the entire material to nbe divided into strands, as shown, must leave the libres on eaclredge of the strandsin a very rough and hairy condition, and the strands must become united again by their elasticity, L nd by the action ofy attraction and electricity, which oftentimes is very great immediately after leaving the saw-disks,' and while the dotl'er is carrying the strands from the disks to theruhbers, a distance, perhaps, of

4about twenty-four'inches, more or less, according to the above arrangement, thus delivering -the strands to the rubber-sin a conjoined and connected condition.

' Our invention and improvement are intended to remedy and correct `all of the above difficulties from whatever cause; and consists in placing a revolving toothed strand-divider just below a dotier provided with rings of card-clothing, and between it and the terial and disks are travelling, so as.:todi\"ide the strands. v Y.

- As the disks travel in the same direction as the material, but slower, the teeth catch the fibres that have connected the strands together, press them sideways, and deliver them to their respective strands and to the rubbers in a more straightened and better divided state. and secured tightly to the shaft at points corresponding With-'the centres of the spaces between the'rings of the doifer, and so that the teeth will point, when revolving, iu an opposite direction to the course of' travel of thedisks, for the purpose of catching the ,fibres (that have been thrown across the spaces be- `tweenthe rings, and connected the strands together,) and carrying them to the rubbers and to their respeetive strands, These teeth will,vby their proximity to therubbers, be etfectnally cleaned by them, thus obviating the necessity for a stripper tokeep them clean.v

In the accompanying drawings- A represents a shaft, placedl just between the doiier B and the rubbers, at thek point where the material is passing from the-dotierte the rubbers, and extending the entire width of the rubbers. It is -provided with a grooved'pnlley, fastened upon one end ofthe shaft., .inside the boxes, to operate-or revolve the shaft, by means of a band.

vFastened permanently on `the shaft A, at points corresponding with the centres of thel spaces on the doi'er, are the disks C', provided with teeth or carriers pointing iu an opposite direction to that inv which the material and disks are travelling.

yAs the disks revolve at aslower ,speed than the dolers and material, t-he teeth or can'iers (l catch the fibres that have been thrown across the spaces 'be- What we claim as new, and desire to secure by? Letters'Patent-, is n The arrangement,with and between a ring-clothed.

doi'er and condeusing-rollers, of a series of toothed sliver-dividin g disks, or their equivalents, having their teeth pointing in an opposite direction to the travel of the material, and' revolving in the direction ofthe travel of the material, but at a slower speed, so as to separate Athe material into slivers,and press the'di-A verging fibres toward the respective strands entering between the.condensiiig-rollers, as described.
